SUPPLEMENTARY INFORMATION:

In general, title 49 United States Code (U.S.C.) section 20157(h) requires FRA to certify that a host railroad's PTC system complies with title 49 Code of Federal Regulations (CFR) part 236, subpart I, before the technology may be operated in revenue service. On December 23, 2020, FRA certified TRE's I–ETMS PTC system under 49 CFR 236.1015 and 49 U.S.C. 20157(h). Pursuant to 49 CFR 236.1035, a railroad must obtain FRA's approval before field testing an uncertified PTC system, or a product of an uncertified PTC system, or any regression testing of a certified PTC system on the general rail system. See49 CFR 236.1035(a). The joint test request, including a complete description of the Concept of Operations and specific test procedures that document the measures that will be taken to ensure safety during testing, are available for review online at https://www.regulations.gov in Docket No. FRA–2010–0044.

Interested parties are invited to comment on the test request by submitting written comments or data. During its review of the test request, FRA will consider any comments or data submitted within the timeline specified in this notice and to the extent practicable. FRA, however, may elect not to respond to any particular comment, and under 49 CFR 236.1035, FRA maintains the authority to approve, approve with conditions, or deny the test request at its sole discretion.
